Brick Buster	“Brick Buster” is a game in which the player earns points by knocking out as many of the bricks in the playing area as possible. On-screen scoring and a high score memory are provided for competitive playing. The active part of the game is written in machine code for fast action. The rest of the	Sinclair ZX81, Timex/Sinclair 1000
Byteing Deeper Into Your Timex Sinclair 1000	Byteing Deeper into Your Timex Sinclair 1000 is catchy title, but do not take it too literally since the book was originally written for the ZX81 and retitled. Nevertheless, the content applies completely to the TS 1000. More importantly though, it does not just “byte” deeper than the User”s Manual, it covers many of the	Timex/Sinclair 1000

Learning Timex Sinclair Basic	If you have ever thrown down your TS1000 User Manual in despair— or disgust, help has finally arrived: David Liens Learning Timex Sinclair Basic. It is a clear, thorough guide to programming the Timex Sinclair 1000, but ZX81 and ZX80 users are not ignored. No matter how “learner friendly” the manual for the new TS1500	Timex/Sinclair 1000

Letters	Payroll: Follow-up to article in v3 n2 Sync; adding printing ability.
Mastering Machine Code on Your ZX81	Though written for the ZX81, Mastering Machine Code on Your ZX81 applies equally well to the Timex Sinclair 1000. Each chapter also includes addressing and programming procedures for the ZX80. The light conversational style is both entertaining and understandable.	Sinclair ZX81, Timex/Sinclair 1000
Memory Scrunching on the TS1000 and ZX81	One of the most serious problems that TS1000 users are faced with (and ZX81 users even more so) is the lack of memory (RAM). Most commercial programs require a 16K RAM pack, and many printed in newsletters and magazines require over 2K (or 1K for ZX81 people). Although the package or listing calls for 16K,	Sinclair ZX81, Timex/Sinclair 1000
Perceptions	The TS2000 series of computers claims an extensive group of features – both hardware and software. The machines feature 24K ROM. The TS2048 has 16K RAM at its disposal while the TS2068 wields a well-utilized 48K RAM.	Timex Computer 2048, Timex/Sinclair 2000, Timex/Sinclair 2068
Quick-draw!	More than two years ago, Sinclair announced that the 4K ROM of the ZX80 would be expanded to an 8K ROM and that one of the new commands would be DRAW. DRAW was just what it sounded like— a command to draw a line on the TV screen. But DRAW never came to be. Even	Timex/Sinclair 1000

The Logical Operators	AND and OR have two distinct usages in Sinclair Basic. One mirrors their use in English and is easily understood; the second is less straightforward, but is an extremely versatile programming technique. NOT, the third logical operator, is unfortunately overlooked or ignored by many beginner programmers; it, too, can be a powerful programming tool.
The ZX Stock Exchange	You have just inherited $10,000 from a wealthy uncle who made it big on the stock market. He also gave you the modem number of his broker, a computer. The ZX Stock Exchange carries stocks listed on the New York Stock Exchange as well as stocks not listed there.	Sinclair ZX81, Timex/Sinclair 1000
The ZX81 Companion	The ZX81 Companion, like other ZX81 books, is totally applicable to the TS1000. It begins with a chapter on graphics techniques. First the screen field is explained. Then PLOT and UNPLOT are used to develop the basic components in graphics: drawing straight lines, using triangles, circles, parabolas, and ellipses, and moving a point around the	Sinclair ZX81, Timex/Sinclair 1000

Using the Byte-Back Modem	The Byte-Back modem is a fine device. It works well and actually does more than advertised. The instruction manual, on the other hand, in its attempt to furnish operating instructions, assembly instructions, and engineering data, is a bit sketchy. A description of the non-standard output on the RS232 board is not given nor is there	Sinclair ZX80
